WebTCP is similar to GBN because both protocols have a limit on the number of unACK'd packets that the sender can send into the network. However, TCP is different from GBN because GBN requires the re-transmission of every unACK'd packet when packets are lost, but TCP only retransmits the oldest unACK'd one.
